Title: Decay heat remover for nuclear reactor
Inventor: KUROKAWA MASAO
IPC: G21C15/18
Filed: 1990-07-31
Abstract: PURPOSE:To achieve a higher reliability along with the simplification of the apparatus by making a magnetic fluid fluidize in a direction of circulation with a permanent magnet depending on a magnetic difference of the magnetic fluid inside and outside a heat shielding area when magnetism of the magnetic fluid lowers within a piping passing outside the heat shielding area. CONSTITUTION:When a temperature of a nuclear reactor rises abnormally or a heat removing capacity of a main cooling system is lost, a temperature of primary coolant (magnetic fluid) of an upper plenum 9 in a nuclear reactor vessel 1 begins to rise abnormally as compared with a normal operation and the coolant flows down on the downstream side (outside a heat shielding area) A of a permanent magnet 8 along the upstream side (inside the heat shielding area) B thereof 8 to heat a coolant in a piping 4 for removing decay heat on the upstream side A. On the other hand, the coolant on the upstream side B does not rise in temperature just as does on the downstream side A because it is surrounded by a heat shielding plate 7a and hence, the magnetism of the cooling material is as given by the upstream side B> downstream side A. As a result, the coolant on the upstream side B is attracted more strongly to the magnet 8 as compared with the coolant on the downstream side A. Thus, a secondary coolant is introduced to a cooling means 6 from the piping 4 to cool and returned to a heat exchanger 3 for removing decay heat through the piping 4 to remove heat in the vessel 1.

Title: Heater for electron tube cathode
Inventor: YAMAUCHI TOSHIYASU
IPC: H01J1/24
Filed: 1986-08-29
Abstract: PURPOSE:To obtain a heater for a cathode with long life and high reliability, by coating a heater core with an alumina layer formed by addition and disper sion of whiskers oblong in shapes and high in strength, and by sintering the core. CONSTITUTION:A mixture formed by adding 15 mol % SiC wiskers 3 to alumina particles 2 is electrodeposited on a W core 1 of a heater and it is coated with a dark alumina layer for improvement of radioactivity and sintered at about 1700 deg.C. A SiC layer is laminated through an alumina layer in which nothing is added, to prevent W from reacting to SiC. when W whickers are used, an alumina layer in an outermost layer of which nothing is mixed is formed to keep insulation between a heater and a cathode. Such composition can suppress generation and development of cracks in the alumina sintering, and disconnection of the core and insulation defects between the heater and the cathode are hardly generated so that the heater's life is prolonged and its reliability is improved.

Title: Rare earth, iron resin-bonded magnet
Inventor: SHIOBARA YUKIHIKO
IPC: H01F1/057
Filed: 1987-08-12
Abstract: PURPOSE:To obtain a magnet which cuts air, moisture, solvent and chemicals and prevents oxidation by covering the surface of a magnet, which is formed by adding a thermosetting resin to magnet powder obtained by a superquick cooling method from rare earth metals, iron and boron and then compressing such powder, with a phenol resin. CONSTITUTION:The surface of a magnet, which has been manufactured by adding a thermosetting resin to magnet powder which has the basic composition consisting of rare earth, iron and boron obtained by a superquick cooling method and compressing such powder, is covered with the phenol resin in the thickness of 0.1-50mum. The phenol resin used has been obtained by reaction of phenol and aldehyde such as formalin under the acidic or alkali catalyst as indicated by the formula I. Such phenol resin shows hardening reaction as indicated by the formula II when it is directly heated or heated under the existence of hexamethylenetetramine. Since it is difficult to attain reliability due to generation of nonuniform layer if the thickness of covering is 0.1mum or less, the thickness is set to 0.1mum or more. Meanwhile, if the thickness exceeds 50mum, the processing time becomes longer, resulting in rise of cost and therefore it is undesirable. Therefore, a magnet which assures high oxidation resistance, excellent stability of magnetic flux and high reliability can be obtained.

Therefore, the service life of the nozzle 1 is extended.
Patent JP-H0250120-A (JP)
Title: Zoom lens
Inventor: SAKA MANAMI
IPC: G02B15/20
Filed: 1988-08-11
Abstract: PURPOSE:To enable high-accuracy automatic focusing over the entire range of zooming by moving a 4th lens element monotonously from an image side to an object side when the zoom lens is focused on an infinite-distance body or from the object side to the image side when the lens is focused on a short- distance body in zooming operation from the wide-angle end to the telephoto end. CONSTITUTION:When the lens is zoomed from the wide-angle end to the telephoto end, the 4th lens element IV shifts in position monotonously from the image side to the object side for the focusing on the infinite-distance body or from the body side to the image side for the focusing on the short-distance body. Namely, the focusing operation is carried out not by a 3rd lens element III as a compensator, but by a 4th lens element IV. Therefore, a tracking curve having no extremal value can be drawn. The tracking curve has no extremal value, so the speed and acceleration of the 4th lens element IV in the zooming are invariably in the same direction. Consequently, various aberrations are compensated excellently over the entire zoom range.

Title: Performance input device for electronic musical instrument
Inventor: TAMURA GENICHI
IPC: G10H1/00
Filed: 1990-07-30
Abstract: PURPOSE:To offer an input device for an electronic musical instrument capable of performance with a performance feeling similar to the performance of a rubbed string instrument by converting a rotating force which is proportional to the movement of a bow and pressure which is proportional to the pressure of the bow into a bow rubbing signal. CONSTITUTION:When the bow 11 is rubbed against a rotary member 21, the rotary member 21 rotates. The pressure of the bow 11 is applied from the rotary member 21 to pressure sensors 23 and 24, which generate signals corresponding to the pressure. The rotation of the rotary member 21 is detected by a rotary encoder 26. The rotary encoder 26 generates a pulse signal corresponding to the angle of rotation. The pressure sensors 23 and 24 include A/D converters. The rotation signal and pressure signal which are thus generated are supplied to a microcomputer 28 through an interface circuit 27, processed, and then supplied as musical sound parameters to a sound source circuit 29. Consequently, the musical sound parameters which are suitable for the generation of the musical sound of the rubbed string instrument can be generated. The bow of the natural musical instrument can be used as a performance means as it is without being processed. Consequently, a player who is skilled in the performance of the rubbed string instrument can play on the electronic musical instrument as it is.
